Signals, Interfaces and Pins

I/O Signals

Overview of the Zynq SoC's PS/PL banks I/O signals connected to the external connectors:

Table 2: Overview of the Zynq SoC's PS/PL banks I/O signals.

JTAG Interface

JTAG access to the Xilinx Zynq XC7Z010 SoC is provided through FTDI USB/UART FIFO bridge connected to the J9 Micro USB connector.

Quad SPI Interface

Quad SPI Flash (U5) is connected to the Zynq PS QSPI0 interface via PS MIO bank 500, pins MIO1 ... MIO6.

Table 3: Quad SPI interface signals and connections.

SD Card Interface

TE0723 module has on-board 3.3V SD Card socket (J10) with card detect switch wired to the SoC PS MIO bank 500.

On-board Peripherals

DDR Memory

TE0723 module has up to 512-MBytes of DDR3L SDRAM arranged into 32-bit wide memory bus providing total of 1 GBytes of on-board RAM. Different memory sizes are available optionally.

Quad SPI Flash Memory

On-board quad SPI Flash memory S25FL127S (U5) is used to store initial FPGA configuration. Besides FPGA configuration, remaining free flash memory can be used for user application storage. All four SPI data lines are connected to the Zynq SoC's PS, allowing x1, x2 or x4 data bus widths. Maximum data rate depends on the bus width and clock frequency used.

Dual High-speed USB to Multipurpose UART/FIFO

FT2232H...

High-speed USB ULPI PHY

Hi-speed USB ULPI PHY (U18) is provided with USB3320 from Microchip. The ULPI interface is connected to the Zynq SoC's PS USB0 via MIO28..39, bank 501 (see also section). The I/O voltage is fixed at 3.3V and PHY reference clock input is supplied from the on-board 52.000000 MHz oscillator (U14).

Power and Power-On Sequence

Power Supply

5V power can be supplied by the external power supply through connector J12 or via USB connection to the host system through USB connector J8 or J9. Minimum current capability of 1A for external power supply is recommended.

Power Consumption

Power consumption is to be determined by the user and depends on SoC's FPGA design and connected hardware.

Power-On Sequence

There is no specific power-on sequence, system will power-up itself if 5V is present either through J8, J9 or J12.
